DYE-SOAP.

No Drawing.

To all whom it may concern:

Be it known that I, LELAND C. GATES, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have discovered a certain new and useful Dye-Soap, of which the following is a specification. V

y invention relates to dyes and particularly to a novel dye soap. 1 7 It is well known that certain of the anilin dyes may be combined with a soap solution to form a product which is capable of performing the two functions of cleansing and dyeing a garment. When such a prod.- uct is properly prepared the operations may be carried out without staining the utensils employed orthe hands of the user. However, when the product is prepared in accordance with the heretofore known practice this result is possible only when a relatively small amount of dye is used; in other Words, only when the garment is to be dyed a light color.

Although much effort has been made to Specification of Letters Patent.

produce a dye soap by means of which dark colors might be secured without staining the hands of the user, such efforts have been unavailing; I have, however, devised a product which has allthe advantages possessed by that heretofore used for dyeing light colors,- and with which even the darkest colors may be produced such dark brown, darlg green and black.

The desired result is secured by preparing a soap base which may be either a boiled kettle soap or a cold process soap. A suitable quantity of the base is placed in a crutcher and heated to approximately 200 F. To this substance is added a solution of sulfonated castor oil, otherwise known as as navy blue Turkey red oil, inwhich the required quantity of the dye to be employed has been dissolved, the mixture being heated to sub-- stantially the boiling point before being added to the soap base. After having been added to the soap the mixture is agitated in the crutcher for a suitable period, usually about thirty minutes, after which it is drawn 01f into a mold or frame and after solidifi cation and cooling is formed into cakes in theusual manner. I

The dyes employed for producing the different colors will, of course, vary in accord ance with the color to be produced. I have employed methylene blue, fast red, chrysoidin Patented June 17, 19119.

yellow, pheno black, and Bisl'narck brown, both separately and in combination. Of course, other anilin colors may be employed, those mentioned being only examples. \Vhen combinations of the different colors are employed they are dissolved separately in a suitable quantity of the sulfonated oil and singly added to the soap base giving time for the preceding color to become at least partially disseminated throughout the mass. In this manner precipitation of the colors will be. avoided. I

Of course, the quantity of dye employed will vary With the quantity of base and with the depth of color desired. In preparing a lot which will result in approximately fortyfive gross of one ounce cakes of dark blue dye, I place in the crutcher approximately thirty-five gallons of the soap base. To this is added twenty-five pounds of-methylene gallons of sulfonated oil and six pounds of fast red dissolved in nine gallons of the sulfonated oil. These proportions,'of course, are only approximate and may be varied within rather wide limits.

It will be-understood that the invention is not limited to the particular sulfonated oil mentioned as undoubtedly other oils having similar properties may be used with equal results. A product made in accordance with the process and by the use of the ingredients mentioned will result in an article which Will dye even the deepest colors without stainingv the hands of the user or the utensils employed. The colors are fast, universal and alkali proof.

I claim:

1. A dye soap composed of the reaction products of a soap, and an anilin dye dissolved in a sulfonated oil, substantially as described. I

2. A dye soap composed of the reaction products of a saponified solution, a quantity of an anilin dye suflicient to produce dark shades, and a sulfonated oil, substantially as described.

8. A dye soap composed of the reaction products of a saponified I, solution, and an anilin dye dissolved in sulftinated castor oil, substantially as described.

4. A dye soap composed of the reaction products of a saponified solution, a quantity of an anilin dye suflicient to produce dark shades, and a sulfonated castor oil, the dye being dissolved in the oil before being added to the sa-ponified solution, substantially asdescribed.

5. The method of making a dye. soap which consists in preparing a saponified solution adding thereto a solution of dye and sulfon'ated oil at a temperature of approximately 200 F., then agitating the mass, and then molding the product, substantially as described.

6. The method 'of making a dye soap which consists in preparing a saponified solution, heating the same to substantially 200 F., adding thereto a solution of dye and sulfonated oil at a temperature of approximately 200 F., then agitating the mass, and then molding the product, substantially as described.

7. The method of making a. dye soap which consists in preparing a saponified solution, then preparing a plurality of solutions of different colors of dye and a sulfonated oil, then separately adding such dye solution to the saponified solution, then agitating the mass, and then molding the same, substantially as described.
